LG Electronics said on the 18th it will launch the LG Premium Ventilation PLUS, a home ventilation system that detects indoor pollution sources based on artificial intelligence (AI) and provides customized ventilation.
A ventilation system is a device that purifies outside air and brings it indoors while expelling polluted indoor air outside. It is mainly used in weather that makes it hard to open windows or in highly airtight residential spaces.
The new product features an AI air quality sensor that detects changes in air in real time. Using AI-learned data on various pollution sources, such as formaldehyde, a cause of sick house syndrome, and volatile organic compounds generated during cooking, this sensor determines indoor air quality. When pollution is detected, the ventilation system automatically operates or increases airflow to improve air quality.
Customers can choose from various ventilation modes depending on indoor and outdoor air conditions. When outside air is pleasant, they can set the Natural breeze ventilation mode that uses outside air, and when only indoor fine dust needs to be removed, they can set the Indoor circulation mode that purifies only indoor air to manage air quality efficiently for the situation.
Purification performance has also been enhanced. The filter uses UV nano sterilization technology to inhibit the growth of bacteria and viruses, such as Staphylococcus aureus and Klebsiella pneumoniae, by 99.99%. The H14-grade HEPA filter removes at least 99.995% of ultrafine particles, and the soot-specialized filter removes harmful gases such as nitrogen dioxide and sulfur dioxide, making it effective for residences near roads.
Energy efficiency has improved as well. The new product is equipped with a high-efficiency total heat exchanger that reduces the heat of hot air coming in from outside in summer and warms cold air in winter. In tests based on KS standards, it recovered about 62%–68% of cooling energy and about 75%–82% of heating energy, helping cut cooling and heating costs.
Ceiling diffusers installed throughout the house automatically open and close according to pollution levels by space—such as the living room, kitchen, and study—and focus ventilation where needed. For example, when pollution in the kitchen increases, the diffusers in the living room and study close and only the kitchen diffuser opens for focused ventilation. Air quality status is indicated by LED colors—▲red (very bad), ▲orange (bad), ▲green (moderate), ▲blue (good)—for easy at-a-glance checks.
Ease of installation and maintenance was also considered. Compared with previous models, the new product reduces the main unit size by about 20%, allowing installation in cramped spaces, and the filter can be replaced with the press of a single button.
Bae Jeong-hyeon, head of the SAC Business Unit at the ES Business Headquarters of LG Electronics (executive vice president), said, "We will further enhance customers' health and quality of life with a smart ventilation solution that delivers pleasant air all year round."
